Hello public.
What type of disk array is it ?.

It sounds like a hardware problem

Did you try doin an ioscan, to see if something is in an NO_HW state ?

[Calandrello]

Friend
when you execute ioscan - FNC disk which the status of records? they exist some in IN _HW? stm one tries to execute way diag in controler.

Hi,

c5t0d0 is going bad. Root cause: disks fail.
